Location and accuracy The location is approximate; it may be on Excelsior Creek about 3.5 miles above its mouth. Cobb (1979 [OF 79-1247]) cites Mulligan (1974, fig. 8) as the source for his location. This location is in the SW1/4, section 33, T. 13 N, R. 2 E., Copper River Meridian. It is possible that the location is farther upstream. The only direct reference to its location is in Mendenhall and Schrader (1903, p.46) who reported that 'further locations have been made in the region between Gakona and Chistochina on Excelsior Creek and the headwaters of the Shnu.' The Shnu is now called Sinona Creek (GU044); it is the next creek east of Excelsior Creek.

Geologic setting

Geologic description

Country rock in the area is mostly volcanic rocks of the Pennsylvanian to Permian, Tetelna Formation. Placer deposits were found in the region in the early 1900s shortly after the discoveries of gold at Slate Creek, Miller Gulch, and other creeks in the Chistochina placer district. Nothing else is known of the deposits which are probably of the river-bar type.

Workings or exploration A small placer operation was noted in this area by Mendenhall and Schrader (1903) but apparently there has been no activity since.
